GEORGE PULLETS, OF NEW YORK, N. Y., ASSIGNOR 0F ONE-HALF TO PAUL RAIA, OF NEW YORK, N. Y.

S'I'EBILIZER.

Application filed September 29, 1915.

To all whom it may concern Be it known that I, GEORGE PULLETS, a subject of the King of Greece, and a resident of the city of New York, borough of the Bronx, in the county of Bronx and State of New York, have invented a new and Improved Sterilizer, of which the following is a full, clear, and exact description.

This invention relates to sterilizing apparatus and has particular reference to an apparatus of this nature designed particularly for use in barber shops for cleansing and sterilizing towels and implements used in such shops.

Among the objects of the invention is to provide an apparatus of a simple, neat, relatively cheap and efiicient character having facilities for insuring a thoroughly sterilized set of towels or implements for each customer and whereby the health department regulations with respect to sanitation in a barber shop may be easily and fully complied with.

With the foregoing and other objects in view, the invention conists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed herein, still for the purpose of illustrating a practical embodi ment thereof reference is had to the accompanying drawings, in which like characters of reference designate the same parts in the several views, and in which Figure 1 is a vertical sectional view of a preferred embodiment of the invention; Figs. 2 and 3 are transverse sections on corresponding lines of Fig. 1; Fig. 4 is an enlarged'vertical sectional view corresponding to a portion of Fig. l but showing a changed position of one of the carriers; Fig. 5 is a horizontal sectional detail just above the razor holder disk; Fig. 6 is a perspective Specification of Letters Patent.

typified by a gas burner 11 beneath the bottom 12 of the boiler. Theapparatus may be adapted to be supported in any suitable manner as upon legs 13. The purpose of the water is to generate steam for heating and sterilizing a quantity of towels or the llke and also for sterilizing brushes, combs, mugs, razors or other implements used in a barber shop, either by plunging the implements into the boiling water or supporting them in any suitable manner in the steam above the water. The boiler is shown as round in plan view and preferably of a cylindrical form having a vertical axis whereby a lid or cover 14 having a flange 14 1s adapted to fit in order to make a substantially. steamtight joint or closure for the top of the boiler, and yet because of the form of the boiler, the cover may be rotated for convenience in getting access to the apparatus or utensils being treated.

At 15 I provide a tubular support attached at its lower end to the bottom 12 of the boiler and extending thence upwardly at the center of the boiler and above the same. Said support 15 serves a number of functions, among which may be noted, first, it is a direct support for a steamer 16 in the form of a drum adapted to contain a quantity of towels 17 and accessible through one or more sliding doors 18 or their equivalent at the front of the steamer. The bottom of the steamer is open and communicates with the open upper end of the support 15, although the towels may be supported upon a reticulated bottom 19 spaced upwardly from the closed bottom portion of the steamer. A second purpose, therefore, of the tubular support 15 is to convey steam admitted thereinto from the upper portion of the boiler through one or more openings 20, the steam passing thence through a tapered collar 21 serving to jet the steam upwardly toward the steamer. A third purpose for the tube 15 is to serve as a guide and support for the crown 22 and elevating devices associated therewith.

At 23 I show a flange secured to the support 15 and adapted to support the central portion of the cover 141 from which there extends upwardly a sleeve 24 carrying said crown. A plurality of guides 25 also extend in parallel relation to one another between the cover 14 and the crown and there by the crown structure is rigidified and the said crown structure is adapted to rotate freely around the main support 15 and upon the top of the boiler.

The crown constitutes a direct support for one or more pulleys 26 each having a flexible line or cord 27 operating thereover. The outer end of each cord has connected to it a slide and finger piece 28 movable along a vertical slot 29 terminating at its lower end in a horizontally disposed bayonet slot 30. The other end of the cord 27 is connected to the top of acage 31 adapted to carry the tools to be sterilized within the boiler. Each cage is preferably constructed, as shown best in Fig. 4, to comprise an upper support 32 and a lower support 33 in vertical alinement, and having an upper plate 34 and a lower plate 35 adapted to constitute closures in alternation for an opening 36 in the top of the boiler and through which the two holders 32 and 33 of the cage are adapted to pass. The plates 34 and 3 5 are connected by rigid bars 37 which const1- tute a rigid framework for the cage. The articles to be sterilized maybe dropped directly into one or the other of the holders 32 and 33 when the cage is elevated as shown in Fig. 4, the particular holder being selected as to whether the articles are plunged into the water or only steam, as suggested in Fig. 1. The cage is held in the upper position with the plate 35 closing the opening 36 to retain the steam within the boiler by means of the interlocking connection between the finger piece 28 and the bayonet slot 30. When, however, the finger piece is unlocked and allowed to slide upwardly along the slot 29, the ca and any articles supported therein will plunge into the water and the opening 36 will then be sealed by the plate 34. For convenient access to any other cage of the apparatus, the crown 22 may be rotated around the vertical axis of the apparatus, and any utensils which may have been previously introduced into the sterilizing bath may be removed. The idle cage may be left elevated as shown in Fig. 4, while the utensils pertaining thereto are being used, since no steam can escape when in such position, or the cage may be immediately filled and plunged into the water again while one set of implements are being used.

At 22 is indicated a knob at the top of the pulley guard which constitutes an ornament and may be used as a means for rotating the crown and cage mechanism.

rovision is made for sterilizing a number of razors independently of the cage devices above described. Referring now eS- pecially to Figs. 5 and 6, I provide around the front portion of the boiler any suitable number of open-front pockets 38 shown as of substantially cylindrical form and built either within or without the boiler. The

essential featur of this razor pocket is a horizontal plate 39 which supports a razor sheath 40 serving to receive and hold the hilt or back of the razor blade with its edge out of contact with any of the structure. The plate 39 is provided with a hole 39 through which the razor is adapted to be projected, but such hole is normally closed by a disk 41 'rotatably connected thereto through a pivot 42. held in closing position by virtue of a spring 43 within a housing 44 carried by the disk, one end of the spring bearing directly against the end of the housing and the other end bearing against a lip 45 struck up from the plate 39. lVhen,however, the razor is to be introduced into the sterilizer, the point of'it is projected into a hole 46 which, upon turning the disk through a small angle, is adapted to be brought into registry with the hole 39 I and sheath 40, and then the razor blade may be plunged directly into the water as shown in Fig 1. The razor blade is held locked in position by the force of the spring 43. The razor, however, may be lifted from the apparatus without obstruction, and the disk will then automatically close the opening 39'. The number of these razor pockets may be great or small, depending upon the number of barbers in the shop or other conditions, and hence while I show but three, it is obvious that I do not wish to be limited in this respect nor in any other minor detail. The purpose of Fig. 9 is to show that in case a smaller boiler is used, the razor pockets 38 may be built upon the outside of the boiler.

The structure of Fig. 8 in all of the principal features is the same as that of Fig. 1. I provide, however, in this modification, that the supporting tube 15 for the cage mechanism shall constitute a separate tank for a body of water and whereby the steam generated therein will not be contaminated by communication with the main body of water in the tank 10.

I claim 1. In a sterilizer, the combination with a boiler and means to heat water therein to form steam, the cover of the boiler having The disk is normally 1 a hole therethrough, of a cage comprising a plate at its upper end and a plate at its lower end, a portion of the cage being projectable into the Water and another portion into the steam space above the water, and means to reciprocate the cage so as to make one or the other of said plates a steamtight closure for the opening in the cover, substantially as set forth.

2. In a sterilizer, the combination with a boiler and means to boil water therein to generate steam, of a central vertical support, a supporting device movable around the vertical support, and cage devices coopcrating with the boiler and controlled by said supporting devices.

3. In a sterilizer, thecombination with a boiler having a rotary cover, of a crown supported in spaced relation above the cover, said cover having holes therethrough, and cage devices movable through said cover holes and including means to seal the holes while the cage devices are either external of the boiler or internal, said cage devices being supported and movable from said crown and rotatable with the cover around the top of the boiler.

4. In a sterilizer, the combination with a boiler, having a vertical central member, means to heat Water in the boiler, of a crown rotatable around the central member, a series of cage devices supported from said crown and movable toward the same through the cover of the boiler, means to lock each of the cage devices in elevated position, and means included in the cage devices to seal the respective openings irrespective of whether the cages are up or down.

5. In a sterilizer, the combination with a boiler having a cover formed with a series of openings therethrough, of a crown supported in spaced relation upon and above said cover, a series of cages operating through said cover openings, means cooperating with each cage to seal the opening through which it is adapted to pass a flexible line connected to the top of each cage and movable thence over the crown, and a finger piece serving to control the operation of each cage, substantially as set forth.

6. In a sterilizer, the combination with a boiler and means to heat water therein to form steam, the upper part of the boiler having a hole therethrough, of a cage comprising a plate at its outer end and a plate at its inner end, a portion of the cage being projectable into the water and another portion into the steam space above the water, and means to move the cage so as to make one or the other of said plates a steamtight closure for the opening in the cover, substantially as set forth.
